8M Rear Panel
1. The 8M is equipped with an auto-switching interna-
tional power supply.
2. BNC word clock jacks. Use them for a variety of applica-
tions, such as digital transfers with devices that cannot
slave to the clock supplied by their digital I/O connection
with the 8M.
3. These ADAT optical “lightpipe” jacks provide 16 channels
of 24-bit ADAT optical digital I/O at 1x sample rates (44.1
or 48 kHz) and 8 channels at 2x sample rates (88.2 or 96
kHz). They are disabled at higher sample rates. The IN
and OUT ports on the right provide channels 1-8 (or 1-4),
and the left-hand ports provide channels 9-16 (or 5-8).
4. The 8M’s eight analog outputs are balanced TRS quarter-
inch connectors that can also accept an unbalanced plug
(with the ring disconnected). They are equipped with
very high quality 24-bit 192 kHz converters. The output
trim can be adjusted from the Output Setting section of
the Device Tab in the MOTU AVB Control web app
software.
5. These XLR/TRS combo jacks accept either a mic cable or a
quarter-inch cable, balanced or unbalanced, from a
guitar or line input. Use the front panel controls to adjust
individual preamp gain, 48V phantom power, and an
optional -20 dB pad for each mic input. The quarter-inch
plug is equipped with a high-impedance circuit for
guitar input.
6. Connect the 8M to the computer here via either
Thunderbolt or USB 2.0, using a standard Thunderbolt or
USB cable. For details, see “Setup for multiple Thunder-
bolt and USB interfaces” on page 39.
7. The AVB Ethernet port provides industry standard IEEE
802.1 network connectivity to other network devices.
Examples include:
■
Another 8M or any other MOTU AVB-equipped device,
such as the 1248 or 16A audio interfaces.
■
A standard Ethernet hub or WiFi router (for internet
connection and communication with the MOTU AVB
Control web app software).
■
A standard AVB Ethernet switch for high-speed, low-
latency, high-capacity audio connectivity to an AVB
audio network.
